I'm not sure if this is really an etiquette question so much as a "business" one. But I would like input as to (a) whether I am being unreasonable to pursue this in the first place, and (b) what my best course of action is going to be if I do pursue it. It's LONG, sorry!
Backstory
My fiance's son (DSS, for simplicity's sake) started middle school in mid-August. He gets 2 blocks of "related arts" in middle school, his choice of strings, band, PE, and/or a foreign language. He chose band as one of his two blocks, and was assigned the trombone as his instrument. We rented his instrument through the company recommended by the school, and he received his instrument at a Saturday "band starter camp" in mid-Seotember. The first week that he had the instrument passed without incident. Monday of the 2nd week he came home from school and told us that his bus driver told him he couldn't bring his instrument on the bus anymore, only clarinets and flutes.
I am a bit of a Type A personality. Before school even started, I read every document and link on his school's webpage. DF and I attended back-to-school orientation, and I read every piece of paper there. DSS came home from his first day of school with a sheath of papers, and I read all those too. This was the first I'd heard that band instruments wouldn't be allowed on the school bus. Just in case I'd missed something though, I re-read the school's website and all the papers from orientation and that DSS had brought home, and dug through the entirety of the district's website. DF did the same. We still couldn't find a policy regarding band instruments on the school bus. So we figured DSS must have misunderstood something.
Tuesday morning we waited for the bus with DSS, and DF asked the bus driver if she could tell us if there had been a misunderstanding, or if DSS was in fact not permitted to bring his trombone on the bus. She told us violins and violas were the only instruments allowed. We asked if DSS would be able to ride the bus that day since this was the first notice we were receiving from her or the school, and needed to arrange alternate transportation, but our request was refused. She gave a phone number to call, so I called while DF took DSS to school. The number was not for anyone at the school, but was for the bussing company that the school contracts with. The woman I spoke to stated that it is district policy that no instruments are allowed on the bus, but that the school and the company had decided to make an exception for violins and violas. She could not tell me where the policy was posted, or why the parents had not been informed.
The Question
At this point, I am of a mind to call the assistant principal or principal, then possibly the superintendent. I am concerned that DSS was assigned an instrument that he cannot continue playing unless we are able to rearrange our schedules to drop him off and pick him up every day. I am concerned that while we can make these arrangements, other parents in the same boat may not be so lucky. I am concerned that a good number of children are not going to be able to participate in the public achool's free band and strings programs because this restriction on bus riders is going to create a barrier to entry. I am concerned that we were not told of this "policy" until a month into the school year, and then it was through DSS as the messenger. I would like to work with the school and/or district to come up with reasonable alternatives or accommodations for bus riders that want to pursue music. Would it be reasonable for me to take this route? If I do, who do I need to talk to, and what should I say?
Thanks eHellions!
